Why we chose it

Calcium is one of those things a caged bird can genuinely run short of without an owner noticing until eggs start coming out thin-shelled, so a soluble grit that dissolves and gets used is worth keeping in stock. A 1kg bag is also a sensible size that doesn't go stale before it's used.

Specifications

Brand: Mr Johnson's

Full description

A caged bird has no way to peck at the ground the way a wild bird would, which is the whole reason grit gets added to an aviary or cage deliberately rather than left to chance.

This is Mr Johnson's Oyster Shell Grit, a soluble grit sold in a 1kg bag. It dissolves in the digestive system, providing extra calcium that Mr Johnson's say supports strong bones and stronger egg shells.

What the label does not say. No feeding rate or how often to top up a grit pot is given, and no guidance on which bird species this particular grit suits best is stated beyond it being a general bird product.

Who it's for: owners of egg-laying birds in particular, where extra calcium for shell strength matters most, as well as anyone keeping a general grit supply topped up.
